Abstract (en)

The presently disclosed subject-matter provides a method for producing a printing sheet, comprising extruding a molten first thermoplastic resin (9) on one surface of a continuously-running transparent substrate (42); nipping the transparent substrate (42) and the first thermoplastic resin (9) with a first cooling roller (2) having a smooth surface which is arranged on a side of the first thermoplastic resin (9) and a first nip roller (3) arranged on a side of the transparent substrate (42); cooling the first thermoplastic resin (9) with the first cooling roller (2) to form a first thermoplastic resin layer; releasing the transparent substrate (42) on which the first thermoplastic resin layer is laminated from the first cooling roller (2); extruding a molten second thermoplastic resin on the other surface of the continuously-running transparent substrate (42); nipping the first thermoplastic resin layer and the second thermoplastic resin with a second cooling roller (13) with a pattern for forming a lens which is arranged on a side of the second thermoplastic resin and a second nip roller (14) arranged on a side of the first thermoplastic resin layer to form a lens on the second thermoplastic resin; cooling the second thermoplastic resin with the second cooling roller (13) to form a second thermoplastic resin layer; and releasing the transparent substrate (42) on which the second thermoplastic resin layer with the lens formed is laminated from the second cooling roller (13).
